There have been brokerages offering flat fees and failed.

Meanwhile, the sellers who are most likely to offer creative financing are normally the owners of  real estate that have issues.....condition.....low barrier/over supply market......or perhaps pricing issue, and one of these factors is why its not marketable in a arms length transaction and why creative financing would be accepted.

I see what you mean about offering a higher return to a potential investor, especially if they are not familiar with my character/experience in the industry. 

I’ve sent the seller a demand letter, but instead of honoring the contract, they offered me money to walk away.

Pro Tip: Ask an insurance agent what your rate will be before you make that offer.

My cost they said i could do $2,000 up front and then next couple months more payments with cold calling they offer and fee would be $9,800 plus the cold callers Virtual assisant that would be working with me.

We take your info and we let Lenders battle for the deal offering their best options.

Never go with one offer. 

Some lenders offer creative solutions, like a cross-collateralized loan, where they use your existing equity as security without refinancing the duplex.Another idea is partnering with private lenders or exploring a second-position mortgage, depending on your lender's terms.

From the information you offered, I researched The Land Method and can clearly see why Jonathan is the way to go.
